BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to the field of packaging, and in particular to a liquid crystal module package box.

2. The Related Arts

In the field of manufacture of liquid crystal display devices, the manufacture of liquid crystal display devices includes a process of assembling, which assembles various components, including a liquid crystal module, a main control circuit, and an enclosure, together. These components are each manufactured in advance and packaged for being later assembled to form a complete liquid crystal display device. It is inevitable that a liquid crystal module may be impacted by external forces and falling during the shipping thereof. To well protect the liquid crystal module, it is desired to add a cushioning structure in a package box to spread acting forces induced by external forces and absorb the impact energy of falling.

A conventional liquid crystal module package box is illustrated in FIG. 1. The package box comprises a box body 100, a bottom cushioning unit 300, and a top cushioning unit 500. The bottom cushioning unit 300 comprises a cushioning bottom board 302, two cushioning side boards 304 that are mounted on the cushioning bottom board 302 and arranged at two ends of the cushioning bottom board 302, and three positioning cushioning boards 306 that are mounted on the cushioning bottom board 302 and arranged, in a spaced manner, between the two cushioning side boards 304. The two cushioning side boards 304 are both provided with a plurality of spaced receiving slots 305. The three positioning cushioning boards 306 are all provided with a plurality of positioning slots 307 corresponding to the receiving slots 305. The top cushioning unit 500 that is used in combination with the bottom cushioning unit 300 has a structure corresponding to that of the bottom cushioning unit 300.

To set up, the bottom cushioning board 302 is first positioned in the box body 100. Next, liquid crystal modules 700 are sequentially fit into the receiving slots 305 and the positioning slots 307. Finally, the top cushioning unit 500 is set on the tops of the liquid crystal modules. It is necessary to fill in some cushioning substances in the process of packaging. Commonly used cushioning components are generally made of foaming materials, such as expandable polyethylene (EPE) and expandable polystyrene (EPS). In minor applications, materials, such as corrugated boards, pulp packagings, and vacuum-formable substances, are used. Cushioning components made of these materials have a high space occupation rate, which affects the cost of transportation.

A newly-developed cushioning material, namely inflatable packaging, is available in the packaging industry. Such a product available from the manufacturers is a film like product. Before use, a user must inflate the product with an air pump to show a tubular like or sack like configuration, which can then be filled between a packaged article and a package box to provide a cushioning effect. It has been proven in the industry that the cushioning effect is similar to the foaming materials. Since it is supplied in a film like form, it is possible to greatly reduce the space needed for warehousing, thereby reducing the cost of use of the cushioning material.

An air column package available in the market is generally used to pack a single article. For packaging of plate-like products, if each plate is individually packaged and then deposited in a package box, then the amount used will be excessive (as shown in FIG. 2). The air column packages 900 used are in the form of a bag and are fit over two ends of a liquid crystal module 700. This makes two layers of air column package 900 present between two liquid crystal modules 700. This results in a waste of the air column package 900 and also increases the overall thickness, which in turn reduces the amount of products to be shipped with a single box and thus increases the transportation cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

To further expound the technical solution adopted in the present invention and the advantages thereof, a detailed description is given to a preferred embodiment of the present invention and the attached drawings.

Referring to FIGS. 2-8, the present invention provides a liquid crystal module package box, which comprises a box body (not shown), two retention racks 2 that are arranged in the box body and opposite to each other, and a plurality of sets of air-cushioning bags 4. To package, liquid crystal modules 6 are positioned between the two retention racks 2 and the plurality of sets of air-cushioning bags 4 is alternately fit over the liquid crystal modules 6.

Each set of air-cushioning bags 4 comprises two bags that are respectively fit over two ends of a liquid crystal module 6.

The retention racks 2 each comprise a first fixing unit 22, a second fixing unit 24 connected to the first fixing unit 22, and a third fixing unit 26 connected to the second fixing unit 24. The first, second, and third fixing units 22, 24, 26 are integrally formed together. Preferably, the first, second, and third fixing units 22, 24, 26 are integrally formed of a foamed cushioning material, corrugated board, or a vacuum-formable material. The first and third fixing units 22, 26 are bent to the same side of the second fixing unit 24 so as to form a U-shaped receiving space 226. The liquid crystal modules 6 are received in the receiving space 226.

The first fixing unit 22 has a side surface that faces the third fixing unit 26 and is provided with a plurality of first cushioning members 222 in a spaced manner. The second fixing unit 24 forms a plurality of second cushioning members 242 in a spaced manner to correspond to the first cushioning members 222. The third fixing unit 26 forms a plurality of third cushioning members 262 in a spaced manner to correspond to the second cushioning members 242. Each of the second cushioning members 242 has two ends respectively connected to the corresponding first and third cushioning members 222, 262 so as to define a plurality of spaced cushioning units 246. A plurality of holding channels 264 is formed between every two cushioning units 246 and between the cushioning units 246 and the box body. The liquid crystal modules 6 are received in or on both the holding channels 264 and the cushioning units 246. The air-cushioning bags 4 are fit over two ends of each of the liquid crystal modules 6 that are received in the holding channels 264. The liquid crystal modules 6 that are positioned on the cushioning units 246 may lean against outside surfaces of the air-cushioning bags 4 to also gain excellent cushioning protection. This arrangement allows only one sheet of the air-cushioning bag 4 to exist between two adjacent ones of the liquid crystal modules 6, effectively reducing the package thickness, increasing the quantity that a single box may transport, thereby effectively lowering down transportation cost.

The air-cushioning bags 4 are each formed by connecting of a plurality of cushioning air columns 42 to form a sheet with opening being sealed with hot pressing.

Referring to FIG. 7, when the air-cushioning bags 4 are fit over the liquid crystal modules, since cushioning air columns 42 are provided at the bottoms of the liquid crystal modules 6, the bottoms of the liquid crystal modules 6 show a difference in height with respect to bottoms of the holding channels 264 at the second fixing unit 24. Similarly, edges of the liquid crystal modules 6 also show a height difference with respect to ends of the holding channels 264 at the first and third fixing units 22, 24. Such height differences are compensated by the cushioning units 246. Preferably, the cushioning air columns 42 have a diameter that is smaller than the height of the second cushioning members 242. More preferably, the sum of the diameter of the cushioning air columns 42 and the thickness of bottom is slightly smaller than or equal to the height of the second cushioning members 242 in order to compensate the height difference between the liquid crystal modules 6 received in the holding channels 264 and the liquid crystal modules 6 positioned on the second cushioning members 242. This ensures flatness and effectively protects the liquid crystal modules 6.

Each of the cushioning air columns 42 has an air-filling hole (not shown) and a sealing device (not shown) that seals the air-filling hole. To transport the air-cushioning bags 4, no air is filled in the cushioning air columns 42 so as to show a flat form, which gives a small space occupation rate and the effectively lower down the transportation cost. To package liquid crystal modules 6, air is filled through the air-filling holes into the cushioning air columns 42 and the sealing devices are applied to seal the air inside the cushioning air column 42 for effective cushioning of the liquid crystal modules to prevent the liquid crystal modules from being damaged by external forces.

The box body can be a paper box or a plastic box, preferably a paper box, to further reduce the transportation cost.

Referring to FIG. 8, which is a schematic view showing an operational flow of packaging liquid crystal modules with the liquid crystal module package box according to the present invention, first of all, the air-cushioning bags 4 are fit over the two ends of one of the liquid crystal modules 6. The liquid crystal module 6 is then fit into the holding channels 264. Next, a liquid crystal module 6 that is not fit with the air-cushioning bags 4 is positioned by the already-mounted liquid crystal module 6 and set on the cushioning unit 246 so that the liquid crystal module 6 that is not fit with the air-cushioning bags 4 leans against outside surfaces of the air-cushioning bags 4. Next, a liquid crystal module 6 that is fit with the air-cushioning bags 4 is mounted in an adjacent holding channel 264. Under this condition, the liquid crystal module 6 that is not fit with the air-cushioning bags 4 are cushioned at opposite sides thereof by the air-cushioning bags 4. This process is repeated to sequentially mount the liquid crystal modules in the retention rack 2 until it is full, where another retention rack 2 is fit to be finally positioned into the box body to complete the packaging operation.

In summary, the present invention provides a liquid crystal module package box, which comprises retention racks and air-cushioning bags arranged inside the box body to effectively protect the liquid crystal modules so as to avoid damages of the liquid crystal modules caused by external forces. Further, the package structure is simple, where air-cushioning bags are alternately fit over the liquid crystal modules to provide a high utilization rate and lower down material cost. Further, the retention racks are provided with cushioning units to effectively cushion the liquid crystal modules and also to eliminate height difference between adjacent ones of the liquid crystal modules so as to ensure flatness and further protect the liquid crystal modules.
